I. If you have never changed the DNS of a domain name
The IP address must have been blocked (buddy! Have you published anything that shouldn't have been released? What should not be collected?Article?)
(There is another possibility that, because foreign companies are more interested in copyrights, they will also take the initiative to block some websites that infringe copyrights)
What should I do? The simplest way is to change the DNS of a domain name.

(Supplement: The above ignores a slightly complex method, that is, Manually changing the record of the corresponding domain name, but if you do not know what to change, I suggest you use the DNS refresh method honestly)
In this way, you don't even need to be surprised to solve the problem on your own.
If you are not using DH domain name resolution, you can change the record of the corresponding domain name.
The following is a wait. The change takes effect. Generally, the change takes effect within 1-2 hours. Be patient and patient.

2. If you have changed the DNS shortly before
It is likely that the error is caused by your change. Because it takes an effective time, the error will be delayed.
Refresh the DNS, and you will find the solution is sometimes very simple.

Refreshing DNS is too easy to use! Very powerful !!
